[Linux-cluster] Conga Error: "... reports its cluster version is rhel4 and we expect rhel5"

[Daniela Anzellotti]

Dear all,

I have two different problems when trying to configure two-node a Cluster:

1. When starting the daemons (using cman startup script), ccsd says
    immediately

  Cluster is not quorate.  Refusing connection.
  Error while processing connect: Connection refused


2. so I tried to modify the cluster configuration by Conga, but I
    received the following error message:

  The following errors occurred:
     * Node <hostname1> reports its cluster version is rhel4 and we
       expect rhel5
     * Node <hostname2> reports its cluster version is rhel4 and we
       expect rhel5



Both the nodes are running Scientific Linux 5.2 with kernel 
2.6.18-92.1.18.el5xen i686

the following rpm are installed:
   modcluster-0.12.0-7.el5
   cluster-cim-0.12.0-7.el5
   lvm2-cluster-2.02.32-4.el5
   cluster-snmp-0.12.0-7.el5
   system-config-cluster-1.0.52-1.1

   cman-devel-2.0.84-2.el5_2.2
   cman-2.0.84-2.el5_2.2

I started configuring the cluster using the tool system-config-cluster.
I wanted a two-node cluster, using a quorum disk as 3rd vote. The quorum 
disk resides on a SAN connected via fiber channel. I inizialized it 
using 'mkqdisk ..." and both nodes can now correctly see it
   root# mkqdisk -L
   mkqdisk v0.5.2
   /dev/sdc1:
         Magic:                eb7a62c2
         Label:                CLUSTER_QDISK
         Created:              Mon Dec 15 19:47:28 2008

         Kernel Sector Size:   512
         Recorded Sector Size: 512


This is the cluster.conf file:

root# cat /etc/cluster/cluster.conf
<?xml version="1.0" ?>
<cluster alias="sicr_vm" config_version="7" name="sicr_vm">
         <cman two_node="0" expected_votes="2"/>
         <quorumd label="CLUSTER_QDISK" interval="2" min_score="1" 
tko="10" votes="1">
                 <heuristic interval="2" program="ping -c 3 
<gateway_IP_address" score="1"/>
         </quorumd>
         <fence_daemon clean_start="0" post_fail_delay="0"

         <clusternodes>
                 <clusternode name="node1" nodeid="1" votes="1">
                         <fence/>
                 </clusternode>
                 <clusternode name="node2" nodeid="2" votes="1">
                         <fence/>
                 </clusternode>
         </clusternodes>
         <fencedevices/>
         <rm>
                 <failoverdomains/>
                 <resources/>
         </rm>
</cluster>



Does anybody can help? I can'tfind where the mistake is...

Thank you,
cheers,
Daniela
